INTERNALQOMBUSTION ENGINE v Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed December 11, 1907. Serial No. 406,075.

To all whom it may concern:

Be it known that I, Jonn Swmrnn Co'r- 'IRELL, citizen of Great Britain,residing at Penshurst, Richmond Hill Road, Edgbaston,

- Birmingham, England, have invented new and useful ImprovementsRelating to Internal-Combustion Engines,of which the following is aspecification.

This invention relates to internal combustion engines of the paraifin orheavy oil type, and has for its object to secure more convenient andeffective utilization of the heat in the exhaust gases for vaporizationof the fuel than is obtainable with the devices ordinarily employed. Ithas been proposed to secure a heater on to the exhaust outlets of anengine and also to arrange in pipe connection with such outlets'a heaterconsistin of a central fuel tube surrounded by an ex aust gas jacket.

Referring to. the accompanying sheet of explanatory drawings:-F1gure 1is a'sectional endelevation and Flg. 2 a sectional plan of a singleheater constructed in accordance with this invention.

The same reference letters in the two views indicate the same or similarparts.-

In carrying the invention into eflect there is employed a case a formedwith suitable flanges b and 0 for connection respectively to the exhaustpipe and the engine cylinder. A central corrugated or ribbed tube d ismountwith end rings e. tion by screwed end caps f rovided with lands 9for the connection 0 pipes h leadmg respectively to the carbureter andeither the engine inlet or another heater. The ca s f operating inconjunction with the tu e rings e and packing rings 71 prevent escape ofexhaust gases from the space around the central tube d. Formulti-cylinder engines one of the devices as above described is mountedon each exhaust outlet, the whole being suitably connected together bypipes. Fuel from an ordinary carbureter enters the tube cl at one endand after passing therethrough issues from the other end to either an adacent heater or the engine inlet according as to whether the engine hasa single or multiple cylinders. With the above apparatus an eflectiveutilization of the exhaust heat for completing the vaporization of thefuel is obtained and uniformity in the quality of the combustiblemixture insured.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is '1. In fuel heating appliances for. internalcombustion engines 0tv the heavy oil type, the combination comprising aflanged heating chamber attachable directly to the exhaust outlet of theengine, a tubemounted transversely within thesaid chamber, end ringssecured to the said tube, detachable end caps serving to maintain thetransverse tube in position, glands formed in the said caps, and pipesinserted in the said glands, substantially-as set forth.

2. In fuel heating a pliances for internal combustion engines of theheavy oil type, the combination comprising a flanged heating chamberattachable directly to the exhaust outlet of the engine, a corrugatedtube mounted transversely within the said chamber, end rings secured tothe said tube, screwed end caps serving to maintain the transverse tubein osition, acking rin s between the caps an rings of the tube, g andsformed in the said caps, and pipes inserted in the said glands,substantially asset forth.

In testimony whereof I have signed my 1
